Hadronic Cross Sections, Elastic Slope And Physical Bounds

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)An almost model-independent parametrization for the ratio of the total hadronic cross section to elastic slope is discussed. Its applicability in studies of asymptotia and analyses of extensive air shower in cosmic-ray physics is also outlined. © 2013 American Institute of Physics.1520297299CNPq,CAPES,CLAF,FAPESP,FAPERJFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)MacDowell, S.W., Martin, A., (1964) Phys.
